VEGE Remanufactured 547B 3.5L 3471cc Premium Grade Long Block Engine

Description

Facing recurring valvetrain fatigue? Select the VEGE 547B Premium Grade Long Block Engine for commercial long block repower projects requiring elevated 3.5L performance. This 3471cc 6-Cylinder unit produces 245HP through a 24-valve single overhead cam architecture. Mechanics must prime the oil passages before initial startup to avoid dry friction on overhead camshaft lobes.

Formed from dense A356 aluminum with pressed cast iron cylinder liners, the engine block joins dual premium aluminum cylinder heads. Each VEGE engine core receives magnetic particle inspection, line honing, and deck surface finishing within 0.0002in flatness. A 12V high torque starter pulls a 195A cranking load during initial startup. Total dry weight equals 388 lbs with a 28in length by 27in width by 26in height mounting stance. Sump oil volume holds 5.0 quarts of 5W-20 oil.

Key Features of VEGE 547B

Maintenance supervisors buy VEGE 547B Premium Grade Long Block units to execute an industrial engine rebuild with guaranteed operational standards. Controlled factory assembly ensures that all critical oil passages and valve rocker hydraulics match blueprint tolerances.

• 3471cc displacement produces 245 ft-lbs torque across broad commercial operating speed ranges.
• Single overhead camshaft per bank actuates 24 valves with hardened stellite seat faces.
• The 547B commercial core receives micro finished cylinder walls for rapid piston ring seating.
• Centrifugally spun iron sleeves isolate combustion heat from the outer aluminum block casting.
• Forged steel connecting rods connect hypereutectic pistons fitted with low friction ring packs.
• Multi layer steel head gaskets resist blow by under continuous heavy payload pulls.
• Heat treated crankshaft main journals maintain runout under 0.0003in total indicator reading.

Dynamic Load Bench Tolerances

On the water brake dynamometer, the 547B long block engine produces 245 continuous BHP at 5,750 RPM and 245 ft-lbs torque at 4,500 RPM. Crankcase oil gallery pressure stabilizes at 60 PSI with oil sump temperatures held at 195°F. Pyrometer gauges measure exhaust gas heat under 1,270°F at sustained high output. Cylinder compression gauges verify 195 PSI across all 6 cylinders with under 3% variance. Main crankshaft journal runout measures 0.0003in TIR, maintaining bearing oil clearances between 0.0011in and 0.0016in.

Field Service Maintenance Rules

Throttle body linkage calls for 5 lbs pull force to ensure responsive plate movement without sticking. Do not install this 3.5L premium grade replacement engine into compressed air compressors or off road construction equipment lacking secondary electronic control units.

• Change engine oil and install new oil filters every 3,000 miles or 150 run hours with 5W-20 motor oil.
• Inspect valvetrain lash and timing belt tension every 15,000 miles to maintain correct valve timing.
• Retorque cylinder head bolts to 76 ft-lbs after the initial 50 operating hours on the machine.

Warranty Terms Crate Contents

VEGE assembly standard warranty rules provide 3-Year or 100,000-mile limited coverage against manufacturing defects. The secured wooden freight crate contains the long block core assembly, aluminum oil pan, oil pickup tube, valve covers, timing cover assembly, and the signed factory dynamometer run report.
